GASOLINE FILTER.

Application filed April 12, 1926. Serial No. 101,240.

invention relates to filters and more particularly to one adapted foruse in connection with a system of cleaning articles of clothing orother fabrics with a fluid, such as gasoline, in continuous flow throughwasher and clarifying elements; the principalobject of the inventionbeing to provide a simple and economical filter whereby water may beseparated from the more volat1le cleaning liquid during circulation ofthe fluid in the system.

In accomplishing this object I have provided improved details ofstructure, the preferred forms of which are illustrated in theaccompanying drawings, wherein Fig. 1 is a central, longitudinal sectionof a filter embodying my improvements.

Fig. 2 is a transverse section of the same.

Fig. 3 is a detail perspective view of a.

filtering material which I prefer to employ with my device.

Referring more in detail to the drawings, 1 and 2 designate sections ofa pipe through which cleaning fluid is circulated in the system and inwhich my filter is interposed.

The filter proper preferably comprises a cylindrical housing 3, having aconical bottom 4, through the apex ofwhich the pipe section 1 isextended to deliver cleaning liquid to the interior of the filter. Re-

movably located within the housin 3 is a screen 5, preferably comprisinga body of wire mesh mounted on end rings 6, of channel iron, the flangesof which are directed outwardly to engage the wall of the housing 3 andspace the screen therefrom in order to provide an outer, annular chamher7 through which the liquid must even-.

tually flow to reach the outlet pipe section 2. Located interiorly ofthe screen 5 is a drum 8, preferably formed of sheet metal havingclosely arranged and relatively small straining apertures 9 in its sidewall, and havin a bottom wall 10 comprising a flange 11 whlch fitssnugly over the pipe section 1 and is flared at its free end to form amouth 12 for guiding the flange 11 over theend of the pipe when the drumis inserted into the housing; the edge of the flange seating within acup 13 attached to and forming a part of the bottom ofthe tank. The drum8 is of substantially less diameter than the screen 5 to form-a chamber14 therebetween.

Enclosing the drum 8 is a strainin jacket 15 preferably consisting ofcotton attlng 16.1ined on both sides with muslin or like fabric 17,through which a thin liquid may pass; but by'which any impurities orsediment contained in the liquid will be caught to effect its separationtherefrom. The bag 15 is preferably closed at its opposite ends by drawstrings 18, the lower one of which surrounds the flange .11 of the drum8 to which it may be tied to securely attach the bag in place.

Located within the drum 8 is a second like drum 19, also composed ofsheet metal having apertures 20 in its side wall and having a closedbottom 21 provided with a sleeve 22, having a flared mouth 23 by whichthe drum is easily fitted over the end of the pipe 1 and spaced from thebottom 10 of" the drum 8. The drum 19 is also enclosed by a fabricfiltering member 24 of construction similar to the covering 15 andprovided with draw strings 25 and 26, the latter serving to tie thefilter member onto the neck of the drum. The drums 8 and 19 are open atthe top but. entirely enclosed by the filtering members 15 and 24, sothat any impure cleaning fluid entering the filter must pass throughsaid filtering members to reach the outlet to the washer, the drumsbeing of progressively lesser height in order that they may be spaced attheir ends to form horizontal chambers at their tops and bottoms, aswell as annular chambers at their sides.

The filter is adapted for vertical arrangement, and in order to eflectthe removal of impurities accumulating in the bottom thereof I make thebottom 3 of the housing as a cone and provide the cone bottom with anoutlet fitting 27 through which sediment or impurities may be drawn andthrough which any water accumtrlated in the filter below the outlet ofthe pipe may be removed. lhe housing 3 is open at the top but normallycoveredcby a lid 28 having a keeper flange fitting snugly within'the topof the housing to prevent accidental displacement of the lid butpermitting removal of the lid when access to the interior of the'filteris desired for cleaning, replacements or other purcorporate the filteras a semipermanent art of the system. The screen 5 is then slid into thehousing from the top with the flanges of of the drum over the pipe 1until the ange seats in the cup 13 where it is held with sufficientfirmness to maintain the drum upright within the housing. .The drum 19with its fabric covering is then lowered into the drum 8, the fabriccovering for the drum Sbeing opened at the end to permit the insertionof the inner drum and then closed by its drawstring.

When these parts are assembled, the lid 28 is applied to the housing tocover the contained elements. When the cleaning liquid is in circulationthrough the system it enters the bottom of the interior drum 28 theapertures in the drum and through the fabric covering into the drum 8,where the filtering process is repeated and the filtered liquid passedinto the chamber 14: and thence through the screen 5 into the chamber 7from which it escapes through the pipe section 2 when'the liquid reachesthe level of the pipe.

It is apparent that by passing the cleaning liquid through the threefiltering bodies the impurities remaining inthe fluid after passagethrough the ordinary clarifier of a system of this 'kind, will beremoved before delivery of the cleaning liquid in the Washer andparticularly will the fabric elements filter out the water from-the morevolatile cleaning liquid.

By arranging the filter elements as deof the housing, concentricallythereof, a screen located within the housing and spaced from the wallthereof, a da drum open at its upper end and having a neck at its lowerend slidable on the intake pipe, the drum having a perforated side walland a fabric ing, a screen located Within the housing and spaced fromthe side wall thereof, aperforated drum open at its upper end andhavinga neckat its lower end fitted over the intake pipe, a fabric coverenclosing said drum, and means removably attaching the cover to the"neck-of the drum. through the pipe 1 and flows out through.

3. A filter of the character described comprising a cylindrical housinghaving a coni- .cal bottom, a feed pipe extending through the bottomconcentrically. of, the housing, a screen located within the housing andspaced from the side wall thereof, a drum having a perforated side walland closed bottom, the

bottom having a neck slidably fitting the intake pipe and having aflared flange seating the drum on the bottom of the housing, the

drum having an open top, and a fabric cov- 3 ering substantiallyenclosing the drum and tied to the neck thereof, 1

4:. A filter of the character described, comprising a cylindricalhousin'g'having a tapered bottom, an intake pipe extending through thebottom, concentrically with the housing and upwardly into the interiorof,

the housing, a on on the bottom of the housing about the intake pipe, adrum hav-- ing a neck fitted over the intake pipe and having a flangeseating in the cup, a fabric member covering the sides and ends of thedrum, andmeans for tying the covering to the neck' of the drum.

In testimony whereof I afiix my signature.
